  The water conduit 18 forms a tubular portion that extends through the front portion 4a of the bowl surface 4 and is connected to a water supply source (not shown) of cleaning water. The water discharge port 12 is configured to communicate with the water conduit 18, and is configured to discharge the wash water supplied via the water conduit 18 from the water discharge port 12 downward. Thereby, as shown by an arrow F in FIG. 1, the cleaning water discharged from the spreader 10 flows so as to spread downward along the front surface portion 4 a of the bowl surface 4, and a part thereof is a side surface of the bowl surface 4. It is led to the front end of the urinal 1 along the part 4b.

  As shown in FIG. 3, cleaning water is supplied to the water conduit 18 from a water supply 32 that is a water supply source via an electromagnetic valve 34. The electromagnetic valve 34 is opened and closed based on a control signal from the control unit 24 at a predetermined timing. The control unit 24 is electrically connected to the first light irradiation device 20 and emits light of a predetermined pattern from the first light irradiation device 20 at a predetermined timing. The control unit 24 is also electrically connected to the second light irradiation device 22 and emits light of a predetermined pattern from the second light irradiation device 22 at a predetermined timing. The control unit 24 performs the washing operation of the urinal 1 and the light emission of the first light irradiation device 20 and the second light irradiation device 22 by a microprocessor, a memory, an interface circuit, and a program (not shown) for operating them. It has a function to control the operation.

  The first light irradiation device 20 is built in the spreader 10. The first light irradiation device 20 projects a light onto the front surface 4a of the bowl surface 4 to form a bright spot T on the bowl surface 4, and the target position on which the user is to apply urine is indicated on the bowl surface 4 Is configured to instruct. Therefore, the urinal 1 has a target position indicating function.

  The first light irradiation device 20 includes a first light emitting diode 36 that is a light source, and a lens 38 that is a light emitting unit that emits light emitted from the first light emitting diode 36 at a predetermined spread angle. . The first light irradiation device 20 is unitized, and the lower end 20 a of the first light irradiation device 20 is disposed in the vicinity of the opening 26. The first light emitting diode 36 is controlled to emit light in a predetermined pattern according to a command from the control unit 24. The first light emitting diode 36 emits blue light, for example. The first light emitting diode 36 may be of a multicolor type capable of changing the color of the emitted light. A circuit board (not shown) to which the first light emitting diode 36 is attached is electrically connected to the control unit 24 by a harness 37.

  The lens 38 is configured and arranged so that light emitted from the lower end of the first light irradiation device 20 is emitted downward with a slight divergence angle around a predetermined optical axis A. The light emitted downward from the lower end 20 a of the first light irradiation device 20 hits a predetermined position on the bowl surface 4 and forms a bright spot T as a target mark on the bowl surface 4. The position of the bright spot T is instructed to the user as a target position to which urine is to be applied.

  As a modification, the first light irradiation device 20 may be a laser diode that irradiates laser light, and the lens 38 is omitted when the first light irradiation device 20 is a laser diode.

  The second light irradiation device 22 irradiates light that indicates the state of the urinal 1 toward the front of the spreader 10. The second light irradiation device 22 includes a second light emitting diode 40 that is a light source, and a circuit board 42 on which the second light emitting diode 40 is provided.

The second light emitting diode 40 is disposed toward the upper front portion of the spreader 10. The light emitted from the second light emitting diode 40 passes through the main body cover part 16 and is emitted in front of the main body cover part 16. The light emitting form of the second light emitting diode 40 changes according to the state of the urinal 1 according to a command from the control unit 24. The second light emitting diode 40 is controlled by the control unit 24 so as to flash and emit light according to the human body detection state of the human body detection sensor, for example, and according to a state such as an error of the control unit 24. Further, for example, when the control unit 24 recognizes the cleaning state of the urinal 1, the second light emitting diode 40 flashes and emits light. Since the blinking light emission pattern is changed to 1 Hz blinking, 2 Hz blinking, twice blinking, or the like according to each state, the user can identify each state of the urinal 1.
The second light emitting diode 40 emits red light. The second light emitting diode 40 may be of a multicolor type that can change the color of the emitted light. The second light emitting diode 40 may be configured by arranging a plurality of LEDs that emit different colors. For example, the control unit 24 may control the second light emitting diode 40 to emit blue light according to the human body detection state of the human body detection sensor and to emit red light according to an error or the like of the control unit 24. The circuit board 42 is electrically connected to the control unit 24 by a harness 44.

  In the front view of the urinal 1, the water discharge port 12 and the first light irradiation device 20 are positioned at overlapping positions in the spreader 10. Moreover, the spout part 12 and the 1st light irradiation apparatus 20 are positioned in the position from which the height of the front direction from the front part 4a differs. In the front view of the urinal 1, the spout 12 and the second light irradiation device 22 are positioned in a position in the spreader 10 that does not overlap. Moreover, the spout part 12 and the 2nd light irradiation apparatus 22 are positioned in the position from which the height of the front direction from the front part 4a differs. The first light irradiation device 20 and the second light irradiation device 22 have substantially the same height from the front surface portion 4a. In addition, the spout part 12 and the 2nd light irradiation apparatus 22 may be positioned in the position which overlaps in the spreader 10 in the front view of the urinal 1.

  Thereby, the spout part 12, the 1st light irradiation apparatus 20, and the 2nd light irradiation apparatus 22 can be arrange | positioned in the inner side space formed with the main body base 14 and the main body cover part 16, and also a spreader 10 can be formed relatively compact. Moreover, the front side of the spout 12 by arranging the spout 12 and the first light irradiator 20 and the second light irradiator 22 at different heights from the front 4a. It is not necessary to arrange the first light irradiation device 20 while avoiding the center position of the bowl surface 4, and the first light irradiation device 20 can be arranged in the center of the bowl surface 4. For this reason, the 1st light irradiation apparatus 20 can irradiate light straight toward the appropriate position of the bowl surface 4, and forms the symmetrical bright spot T on the bowl surface 4 easily. Can do. The water discharge part 12 is arrange | positioned in the front part 4a vicinity, and the 1st light irradiation apparatus 20 is arrange | positioned in the front side of the water discharge part 12 (at the position spaced apart from the front part 4a rather than the water discharge part 12).

  Thus, in the case where the spreader 10 includes the first light irradiation device 20 and the second light irradiation device 22 in addition to the water discharge port 12 that discharges the cleaning water, the spreader 10 is further moved in the front-rear direction. The second light irradiation device 22 is disposed on the side of or above the first light irradiation device 20 inside the spreader 10 so as to be thin and compact, and further, the first light irradiation device 20 and the second light irradiation. A blocking portion 46 is provided between the device 22 and the apparatus 22.

In the inner space formed by the main body base portion 14 and the main body cover portion 16, the first light irradiation device 20 is disposed at the left and right center. In the inner space, the second light irradiation device 22 is disposed above the lower end 20 a of the first light irradiation device 20. The second light irradiation device 22 may be disposed above the side of the first light irradiation device 20. Since the 2nd light irradiation apparatus 22 is arrange | positioned to the side or upper direction of the 1st light irradiation apparatus 20, the height from the front part 4a of the 2nd light irradiation apparatus 22 and the 1st light irradiation apparatus 20 is made into the substantially same height. be able to. Therefore, even if the 1st light irradiation apparatus 20 and the 2nd light irradiation apparatus 22 are incorporated, it can suppress that the spreader 10 becomes thick in the front-back direction, and the spreader 10 can be reduced in size and thickness.
Further, even if the second light irradiation device 22 is arranged close to the side or upper side of the first light irradiation device 20 so as to make the spreader 10 smaller and thinner, the first light irradiation device 20 and the second light irradiation device 20 By providing the blocking unit 46 between the light irradiation device 22 and the light irradiated from the second light irradiation device 22 can be prevented from being mixed with the light irradiated from the first light irradiation device 20. Furthermore, it can suppress that the light irradiated from the 2nd light irradiation apparatus 22 influences the intensity | strength and color of the light irradiated from the 1st light irradiation apparatus 20. FIG.

  The blocking unit 46 is located between the first light irradiation device 20 and the second light irradiation device 22. The blocking portion 46 extends from the main body base portion 14 to the main body cover portion 16 substantially horizontally in the front-rear direction. The blocking portion 46 forms a substantially horizontal plate-like portion along the lower side of the circuit board 42 when the spreader 10 is viewed from the front. The blocking unit 46 forms a wall portion that divides the first space 28 in which the first light irradiation device 20 is disposed and the second space 30 in which the second light irradiation device 22 is disposed. The blocking unit 46 prevents light emitted from the second light emitting diode 40 of the second light irradiation device 22 from leaking into the first space 28 on the first light irradiation device 20 side. Therefore, the light of the 2nd light irradiation apparatus 22 can be guide | induced toward the front of the spreader 10 more efficiently, the fall of illumination intensity can be suppressed and the fall of the intensity | strength of the irradiated light can be suppressed.

  A gap may be formed between the blocking part 46 and the main body cover part 16. Therefore, the blocking part 46 may be formed to extend from the circuit board 42 to a predetermined distance ahead of the second light emitting diode 40 on the circuit board 42. At this time, the gap between the blocking part 46 and the main body cover part 16 is formed in such a size that the light emitted from the second light emitting diode 40 hardly leaks into the first space 28 on the lower side through this gap.

Since the blocking part 46 is formed integrally with the main body base 14, an attachment member for attaching the blocking part 46 to the main body base 14 can be omitted, the main body base 14 can be reduced in size, and the spreader 10 can be reduced in size. Can be
The blocking unit 46 forms part of a section filled with a potting material that covers the circuit board 42 of the second light irradiation device 22. More specifically, the blocking part 46 forms a wall part on the first light irradiation device 20 side among the wall parts formed so as to surround the circuit board 42. Therefore, the blocking part 46 forms a part of the container filled with the potting material, and can store and cure the potting resin in the liquid state. The second space 30 in which the second light irradiation device 22 is disposed is formed by the circuit board 42, the main body cover portion 16, the main body base portion 14, and the blocking portion 46, filled with potting material, and the potting 48 is in the second space 30. It is formed so as to fill almost the whole or a part. Therefore, the potting 48 can prevent the circuit board 42 of the second light irradiation device 22 from being wetted and can improve the waterproofness. Further, since the blocking part 46 also serves as a part of the container filled with the potting material, it is not necessary to attach a member forming the container in addition to the blocking part 46, the number of members can be reduced, and the spreader 10 can be made inexpensive. And can be miniaturized.

  In addition, the main body base 14 of the spreader 10 includes a first space 28 in which the first light irradiation device 20 is disposed and a second space 30 in which the second light irradiation device 22 is disposed, and a water conduit 18 that extends to the water discharge port 12. A partition wall 50 is provided. The partition wall 50 forms a wall surface extending in the left-right direction in front of the water discharge port 12 and behind the first light irradiation device 20 and the second light irradiation device 22. Therefore, it can suppress that each of the 1st light irradiation apparatus 20 and the 2nd light irradiation apparatus 22 gets wet, and a water droplet adheres to the 1st light irradiation apparatus 20 and the 2nd light irradiation apparatus 22. Thereby, it can suppress that the light irradiated from the 1st light irradiation apparatus 20 and the 2nd light irradiation apparatus 22 blurs with a water droplet.

The blocking portion 146 extends from the main body cover portion 16 to the main body base portion 14 substantially horizontally in the front-rear direction. The blocking portion 146 forms a substantially horizontal plate-like portion along the lower side of the circuit board 42 when the spreader 10 is viewed from the front. The blocking unit 146 forms a wall portion that divides the first space 28 in which the first light irradiation device 20 is disposed and the second space 30 in which the second light irradiation device 22 is disposed. The blocking unit 146 prevents light emitted from the second light emitting diode 40 of the second light irradiation device 22 from leaking into the first space 28 on the first light irradiation device 20 side. The light of the 2nd light irradiation apparatus 22 can be guide | induced toward the front of the spreader 10 more efficiently, the fall of illumination intensity can be suppressed and the fall of the intensity | strength of the irradiated light can be suppressed.

  The blocking unit 146 forms part of a section filled with a potting material that covers the circuit board 42 of the second light irradiation device 22. More specifically, the blocking portion 146 forms a wall portion on the first light irradiation device 20 side among the wall portions formed so as to surround the circuit board 42. Therefore, the blocking part 146 forms a part of the container filled with the potting material, and can store and cure the potting resin in the liquid state.
